A machine-side automated device, such as a sliding table or turntable then passes this brought film roll in the danger area or in the protective housing of the injection molding machine. From there, the film roll is transported in the vicinity of the film roll to be replaced (empty roll). After notification that the roll in the production cycle is running empty, the film change process starts automatically. This process i. the method may include the following steps:

First, the injection molding machine moves to close tool in the fully automatic process and starts the next injection process. During the next cycle, the engaged film is clamped by a clamping device. The clamping device can be formed by a separate clamping device, in particular by a different clamping device from the mold clamping plates of the injection molding machine. The separate clamping device can for example be fastened directly to one of the platens or fastened to the IMD foil web feed device, which in turn is connected to one of the platens. The clamping device can also be formed by the platens themselves. In this case, the clamping device can be formed by the platens as far as by the collapsed, i. for injection molding closed platens or injection mold halves, the film between the two platens or injection mold halves is clamped. A clamping of the film according to the invention can thus be formed either by a separate clamping device or by the mold platens or Spritzgießwerkzeughälften. Alternatively, the clamping device may be formed by a combination of a separate clamping device with an additional clamping by the mold mounting plates or the Spritzgießwerkzeughälften. The film engaged during the injection molding cycle and clamped by the clamping device is separated from the residual roll. Thereafter, the remaining roll is removed from the unwinding and discharged from the injection molding machine or from the security area. Subsequently, the new film roll can be placed on the unwinding device and connected to the clamped film residue. An automated connection can be done for example by gluing, welding or stapling. Then the system is ready for use again. This change can take place in particular during the injection process, so that no standstill of the injection molding machine is required to change the film roll.
